Title: Magneto-resistance effect type thin-film magnetic head
Inventor: SASAKI MAMORU
IPC: G11B5/39
Filed: 1991-10-08
Abstract: PURPOSE:To stabilize characteristics and to decrease Barkhasen noises by forming patterns having a narrow front end for regulating a track width by a thin-film magnetic core of a lower layer. CONSTITUTION:The lower layer thin-film magnetic core 3 and the upper layer thin-film magnetic core 4 are so laminated as to form a magnetic gap (g) on the contact surfaces or opposite surfaces of a magnetic recording medium (not shown in Fig.), for example, the ABS surfaces 2 of the slider of a floating type magnetic head, between the respective front ends on a base body 1. An MR magnetosensitive part 5 is disposed between the lower and upper layer thin-film magnetic cores 3, 4 over the inside of the magnetic gap (g). The width at the front end forming the magnetic gap (g) of the lower layer thin-film magnetic core 3 is selected to regulate the track width WT of the magnetic gap (g) and the width at the front end forming the magnetic gap (g) of the upper layer thin-film magnetic core 4 is selected at the width sufficiently larger than the similar front end of the lower layer thin-film magnetic core 3. The sensitivity is improved in this way and the Barkhausen noises are decreased.

Title: Gas broiler
Inventor: KOBAYASHI TOSHIHIRO
IPC: A47J37/06
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To illuminate the inside of a broiler with a simple structure and at a low cost.

Title: Access controller and entry and exiting management device
Inventor: IKEGAWA TOSHIO
IPC: G06F21/34
Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To provide the access controller and entry and existing management device which can make the signal processing of an information processor efficient while minimizing a rise in cost. SOLUTION: Even when a burglar prevention sensor 4 outputs a signal, the signal is not outputted to the information processor 20 unless a burglar prevention alert is set, but outputted to the information processor 20 for a certain time when the burglar preventive alert is started. Consequently, the amount of the signal sent to the information processor 20 is reduced, so the load on the information processor 20 is lightened to improve the responsiveness of the information processor 20. Further, the signal from a burglar preventive sensor 4 is outputted for a certain time and then it can be confirmed whether the signal from the burglar prevention center 4 is a burst or intermittent, so it can be decided whether the signal is sent due to temporary malfunction of the sensor or the wandering of a robber.

Title: Circuit for zero voltage-zero current switching for full-bridge dc-dc converter which can reduce ripple in output current
Inventor: HAKU SHIYUUGEN
IPC: H02M3/28
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To reduce the ripple in output current by making a circuit configuration in such a one that current of inductor for filtering in a DC-DC converter may be allowed to flow in a secondary winding of the inductor or a closed circuit to charge the output terminal of a rectifier to the positive potential. SOLUTION: In the case that an inductor Lo of an output filter is sufficiently large and a passive capacitor C100 is charged with load current Io being constant in one cycle of switching, the turn ratio of secondary windings Lo of the inductor Lo for filtering is so set that charging voltage may not exceed the output terminal voltage of a full-bridge rectifier BD10. Phase advancing switches S1, S3 are switched at zero voltage and phase lagging switches S2, S4 are switched at zero current. Application voltages to leakage inductance of each winding are the same and therefore ripple currents in each winding are reversely proportional. By this method, a ripple current component flowing into a load Ro through a primary winding can be reduced by properly setting the path of ripple current of a capacitor and the inductor.

Title: Ignitor for multicylinder internal combustion engine
Inventor: OKUDA KOJI
IPC: F02P3/08
Filed: 1986-10-31
Abstract: PURPOSE:To obtain the stable ignition timing and prevent erroneous operation by using a noise masking circuit together with zero cross ignition. CONSTITUTION:A switching means operated by the voltage of a power source spark coil and the voltage of a signal coil is used so that mask is released in the front half cycle among the wave forms in the continuous one cycle of the signal coils 16 and 19, and the power source spark coil 1 starts charge for condensers 58 and 59 and at the same time, masking is performed again. Thus, the erroneous operation due to noise can be prevented. Further, a voltage comparator 28 is installed into a signal circuit, and the ignition signal on the basis of the detection of zero cross of the voltage of the signal coil is outputted by increasing the signal bias voltage higher than the standard voltage. Since the generated voltage of the signal coils 16 and 19 is generated also immediately after the ignition timing of other cylinders, added with the regular ignition timing, the regular cylinder is triggered necessarily earlier than other cylinders when mask is released, and the erroneous distribution due to noise can be prevented.

Title: Laser oscillator
Inventor: TERAI KIYOHISA
IPC: H01S3/08
Filed: 1992-09-30
Abstract: PURPOSE:To obtain a laser oscillator which has an excellent light condensing efficiency and high laser oscillation efficiency.

The reflecting surface of the mirror 13 is coated with a nonreflective coating layer 19 at peripheral part and reflectivity variable coating layer 22 the reflectivity of which becomes smaller as going toward the periphery from the center at the central part. Since laser light can be partially transmitted through the central part of the mirror 13 coated with the coating 22 and the transmissivity of the central part varies, the title laser oscillator can output laser light having a gentle power distribution. Therefore, the light condensing ability of laser oscillation efficiency of the laser oscillator can be improved.
